The Heart of the World (Sisyphus)

The first twelve years of Lily’s life were uneventful. She died when she was five, and a few more times after that, but it never seemed to stick. She met Death, another version of her from a different dimension, every Sunday for tea, but was always back in school on Monday. She met an extra-dimensional revolutionary living inside her head, but apart from making her run errands for him all the time he wasn’t up to much either.

When she was twelve, however, things finally took an exciting turn. She was stolen away to another dimension, where they needed her to join in a glorious quest for the Heart of the World.

Sadly for Lily, the quest turned out to be more dangerous than advertised, and her loyalties less easily navigated than she'd hoped.
